flutter_lc_im 0.0.4

A LeanClound IM flutter plugin project.

flutter_lc_im

简单封装了LeanCloud的IM功能，给出了单聊和获取会话列表用户ID的功能。flutter_lc_im 0.0.2

Flutter中的实现如下：

    FlutterLcIm.register("appId", "appKey","当前用户的userId");
    Map user = {'name':'jason1','user_id':"1",'avatar_url':"http://thirdqq.qlogo.cn/g?b=oidb&k=h22EA0NsicnjEqG4OEcqKyg&s=100"};
    Map peer = {'name':'jason2','user_id':"3",'avatar_url':"http://thirdqq.qlogo.cn/g?b=oidb&k=h22EA0NsicnjEqG4OEcqKyg&s=100"};
    FlutterLcIm.pushToConversationView(user,peer);
    FlutterLcIm.getConversationList()

FlutterLcIm.pushToConversationView中第一个参数user指的是当前用户，第二个参数peer是聊天对象.

</plist>

第二步 AppDelegate.m中加入以下代码：

#import <ChatKit/LCChatKit.h>
#import <UserNotifications/UserNotifications.h>

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [AVOSCloud handleRemoteNotificationsWithDeviceToken:deviceToken];
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    if (application.applicationState == UIApplicationStateActive) {
    } else {

        [[LCChatKit sharedInstance] didReceiveRemoteNotification:userInfo];
    }
}

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
    return YES;
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return YES;
}


/**
 * Required for iOS 10+
 * 在前台收到推送内容, 执行的方法
 */
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
    NSDictionary *userInfo = notification.request.content.userInfo;
    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        //TODO:处理远程推送内容
        NSLog(@"%@", userInfo);
    }
    // 需要执行这个方法，选择是否提醒用户，有 Badge、Sound、Alert 三种类型可以选择设置
    completionHandler(UNNotificationPresentationOptionAlert);
}

/*!
 * Required for iOS 7+
 */
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    //TODO:处理远程推送内容
    NSLog(@"%@", userInfo);
    // Must be called when finished
    completionHandler(UIBackgroundFetchResultNewData);
}

 */
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"%s\n[无法注册远程提醒, 错误信息]\nline:%@\n-----\n%@\n\n", __func__, @(__LINE__), error);
}

第三步 Flutter项目中加入以下代码：

    FlutterLcIm.register("appId", "Appkey");
    FlutterLcIm.pushToConversationView(user,peer);
